Yep... I went through about 10 sets to get the ones that felt right and worked correctly. I chose the grease zerk'd bushings as I was trying to rid the VX of the squeak coming from OEM bushings. I could power wash them out, take them off and clean them to no avail. The squeak always came back. The handling change was an added benefit. I no longer have a source for the bushings so I can't order them.

The part numbers are;

Energy Suspension

9.5156G 3/4" (19mm) Rear

9.5163G 28mm Front

Good luck in the hunt.
